I heard about this yesterday, but I forgot to mention it. James Van Allen is kind of a Legend around here. I've had several classes in the Van Allen building and it's a bit hard to believe that he's dead now.

Man who discovered Van Allen Belts dies

IOWA CITY, Iowa (AP) -- Physicist James A. Van Allen, a leader in space exploration who discovered the radiation belts surrounding the Earth that now bear his name, died Wednesday. He was 91.

The University of Iowa, where he taught for years, announced the death in a statement on its Web site.

In a career that stretched over more than a half-century, Van Allen designed scientific instruments for dozens of research flights, first with small rockets and balloons, and eventually with space probes that traveled to distant planets and beyond.

Van Allen gained global attention in the late 1950s when instruments he designed and placed aboard the first U.S. satellite, Explorer I, discovered the bands of intense radiation that surround the earth, now known as the Van Allen Belts.

The bands spawned a whole new field of research known as magnetospheric physics, an area of study that now involves more than 1,000 investigators in more than 20 countries.

The discovery also propelled the United States in its space exploration race with the Soviet Union and prompted Time magazine to put Van Allen on the cover of its May 4, 1959, issue.

The folksy, pipe-smoking scientist, called "Van" by friends, retired from full-time teaching in 1985. But he continued to write, oversee research, counsel students and monitor data gathered by satellites. He worked in a large, cluttered corner office on the seventh floor of the physics and astronomy building that bears his name.

"Jim Van Allen was a good friend of our family. His loss saddens Christie and me," Gov. Tom Vilsack said. "His passing is a sad day for science in America and the world.

Though he was an early advocate of a concerted national space program, Van Allen was a strong critic of most manned space projects, once dismissing the U.S. proposal for a manned space station "speculative and ... poorly founded."

Explorer 1, which weighed just 31 pounds, was launched January 31, 1958, during an emotional time just after the Sputnik launches by the Soviet Union created new Cold War fears. The instruments that Van Allen developed for the mission were tiny Geiger counters to measure radiation.

Near the 35th anniversary of the launch, Van Allen recalled in an Associated Press interview how scientists waited tensely for confirmation the satellite was in orbit.

When the signal finally came, "it was exhilarating. ... That was the big break, knowing it had made it around the Earth, that it was actually in orbit."

The success of the flight created nationwide celebration. Equally exciting for the scientists was the discovery of the radiation belts, a discovery that happened slowly over the next weeks and months as they pieced together data coming from the satellite.

"We had discovered a whole new phenomenon which had not been known or predicted before," Van Allen said. "We were really on top of the world, professionally speaking." Later in 1958, another scientist proposed naming the belts for Van Allen.

His later projects included the Pioneer 10 and 11 flights, which studied the radiation belts of Jupiter in 1973 and 1974 and the radiation belts of Saturn in 1979.

Van Allen continued to monitor data from the Pioneer 10 spacecraft for decades as it became the most remote manmade object, billions of miles away.

Closer to Earth, satellites had revolutionized communications, military surveillance and environmental monitoring. Asked in 1993 whether he envisioned the era of satellite communications, he said: "I guess the honest answer is not really, but I'm not astonished. That sort of thing was kicking around."

In 1987, President Reagan presented Van Allen with the National Medal of Science, the nation's highest honor for scientific achievement.

Two years later, Van Allen received the Crafoord Prize, awarded by the Royal Swedish Academy of Sciences in Stockholm each year since 1982 for scientific research in areas not recognized by the Nobel Prizes.

Besides the discovery of the Van Allen belts, the academy cited him for providing the first instruments carried near another planet, those taken on the 1962 Venus mission by Mariner 2, and for his work training other space researchers.

"I love to work and I love this subject," he said in 1993. As for quitting, he said, "not as long as I'm able I won't."

Van Allen was born September 7, 1914, in Mount Pleasant, Iowa. As an undergraduate at Iowa Wesleyan College, he helped prepare research instruments for the Byrd Antarctic Expedition. He got his master's and Ph.D. from the University of Iowa.

After serving in the Naval Reserve during World War II, he was a researcher at Johns Hopkins University in Baltimore, supervising tests of captured German V-2 rockets and developing similar rockets to probe the upper atmosphere.

One of the highlights of this early research was the 1953 discovery of electrons believed to be the driving force behind the northern and southern lights.

Through his career, he continued to advocate unmanned satellites, once telling a panel that manned space programs have been beset by cost overruns but unmanned rockets "have delivered on their promises and have gone far beyond them."

In testimony before a House subcommittee in 1985, Van Allen said that President Reagan's endorsement of a $20 billion manned space station project was "so speculative and so poorly founded that no one of lesser stature would have dared mention it to an informed audience."

In 2004, he spoke out again, arguing against Bush administration plans for a space station on the moon and a manned mission to Mars.

"I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results," he said.

Van Allen was named to the National Academy of Sciences in 1959. He also was a consultant to the U.S. Congress Office of Technology Assessment, NASA and the Space Studies Board of the National Academy of Sciences.

Yeah, I read that in this morning's paper. "Aw," I said, scanning the article, "Van Allen died." "Who is she?" Wing2 asked. "He," I replied, "was a great man who told us about the radiation shields around the Earth called the Van Allen belts." She didn't care. She will. Oh yes, she will. *cackles maniacally*

It is interesting that he prefered robots over people. He is dead on (ha, okay that was bad) with the underfunded aspect. Maybe if we pumped more money into robots, the unmanned would be more useful.

Actually, pumping more money into NASA is pretty useless. I have seen how that place is run. It is an agency created to suck up money. I am very disappointed in NASA. Disillusioned in another word for it. They need a total overhaul before they are going to be anything other than marginally useful. Their results are only stunning because it is space. If they dealt with anything less spectacular by definition, they would have been scrapped long ago._________________Before God created Las he pondered on all the aspects a woman might have, he considered which ones would look good super-inflated and which ones to leave alone.
